The static mixer comprises a tube body, a tight nut and mixing units; wherein the mixing units are arranged in the tube body; each mixing unit consists of two crossly distributed spiral flow deflectors, two obliquesplitters, two homogenization splitting tubesheet and a mixing neutral block in sequence; the spiral flow deflector is a slabbing spiral steel sheet; the oblique splitter consists of a plurality of m etal sheets which have irregular surfaces which are bended by machine and packed together by thin steel wires; the homogenization splitting tubesheet is a round thin steel sheet, and a plurality of round through holes with the same size are well-distributed on the round thin steel sheet; the mixing neutral block is a cylinder, a through hole is arranged inside the cylinder, and two ends of the cylinder are provided with conical inclined planes.
Description
Technical field
What the above static mixer for liquid of the present invention's two components related to is a kind of small-sized high pressure resistant tubular liquid static mixer, and inside is made of the mixed cell more than three groups.Be specially adapted to carbon dioxide XPS polystyrene extruded sheet material and produce the usefulness of the mixing of central carbon dioxide combined foaming agent blowing agent, also can be used on the mixing of different component blowing agents.
Background technology
The mixing homogenizing carbon dioxide combined foaming agent that is used for the flow-like material in the middle of XPS extrusion molding industry is to be made of the chemical substance more than two components, is to do the blowing agent proportioning with carbon dioxide and alcohols or alkanes to form.And in production technology in the past, when being blowing agent, can't make it is fully evenly mixed, thereby produced that the sheet material cell size differs, degradation phenomenon under the compression strength with the carbon dioxide combined foaming agent.
Summary of the invention
The present invention seeks to provides a kind of two components above static mixer for liquid at above-mentioned weak point, carbon dioxide combined foaming agent is by the chemical substance more than two components, carbon dioxide and alcohols or alkanes are done the blowing agent proportioning and are formed, the present invention is mainly in order to overcome the problem of the undercompounding of different component chemical substance in the production technology, utilization is fixed on the unique texture of each mixed cell in the body, change the flow regime of liquid in body, to reach fine dispersion and well-mixed purpose between the different liquids.
The above static mixer for liquid of two components is to take following scheme to realize: the above static mixer for liquid of two components comprises body, clamp nut and mixed cell; Mixed cell is contained in the body, and wherein each mixed cell is made of successively the spiral flow deflector of two cross-distribution, two oblique splitters, two homogenizing shunting cards and a mixing neutralization piece respectively.
Described spiral flow deflector is a slabbing spirality sheet metal.
Described oblique splitter adopts finer wire that it is banded together composition by the sheet metal of multi-disc surface imperfection through mechanical bending, and the sheet metal surface of process bending is oblique state.
Described homogenizing shunting card is a round thin steel, the manhole of uniform a plurality of identical sizes on round thin steel.
Described mixing neutralization piece is cylindrical, and there is a diameter through hole inboard, and two ends are processed with tapered slope.
Operation principle of the present invention: liquid stream through the process of this liquid static mixer is:
1, the uneven carbon dioxide combined foaming agent liquid of mixing flows to into shunting mixer (this part is made up of two spiral flow deflectors, the body of packing into behind 90 ° of butt welding in spot of one-tenth when packing into) and changes shunting, mixing that fluid flow direction is finished preliminary liquid stream;
2, cross homogenizing shunting card through shunting, mixed liquid communication and shunt homogenizing;
3, flow to into oblique splitter through the liquid after the shunting homogenizing, the shunting of carrying out a dark step mixes;
4, liquid stream enters homogenizing shunting card once more and shunts homogenizing once more;
5, the liquid after the shunting homogenizing flows to the neutralization of gathering of finishing liquid stream into mixing neutralization piece;
6, after liquid stream is finished above-mentioned reaction, enter next group mixed cell.This serial reaction carries out in a plurality of mixed cells successively repeatedly.
The directly situation of decision plate material forming that whether mixes of blowing agent under conditions permit, can change the design length of this invention as required in actual applications.Also can change the diameter of inboard wall of tube body outer wall, mix that fluid flows smooth and easy in static mixer thereby reach according to the flow velocity size of liquid, pressure size.
This invention radially or the change of axial dimension can make the molding effect of sheet material even more ideal.
Described mixed cell is a kind of assembly that does not have the efficient mixing of moving component, can effectively solve to mix unequal problem in application.The quantity of mixed cell must not be less than three groups, through practical application proof mixed cell lazy weight the above blowing agent of two components can't fully be mixed.
The above static mixer for liquid of the present invention's two components is reasonable in design, compact conformation, it is a kind of high-efficiency mixing device that does not have moving component, its groundwork mechanism is to utilize the unique texture that is fixed on each single part in the pipe to change the flow direction of fluid in pipe, to reach fine dispersion and well-mixed purpose between the different fluid.Be specially adapted to carbon dioxide XPS polystyrene extruded sheet material and produce the usefulness of the mixing of central carbon dioxide combined foaming agent blowing agent, also can be used on the mixing of different component blowing agents.
